Step 2: PCB Design

I have prepare PCB layout in fritzing software then Designe a PCB and export its gerber file

This gerber file uploaded to Jlcpcb.com to order the PCB as soon as you recived PCB you need to solder some female header pins to mount arduino nano, LCD display & A4988 driver also solder the PCB terminal to connect power supply to the PCB and to connect stepper motor to PCB here I attached the editable PLC layout file so if you can do any modification required.

Step 3: Procedure

So as soon as all the components are available you can start assembly the machine.

For the base of the machine I used 3MM thick white acrylic sheet

I drill some hole on sheet to mount PCB, Stepper motor with extruder set, cutter & servo motor for better idea please watch video it will give a idea how to mount those components on sheet all the components are tightly mount on the sheet now we can move to program our arduino

Step 4: Arduino Program

Upload the code to the arduino

Now connect the 12V DC at terminal of PCB this is for stepper motor and connect USB to arduino nano this will feed power to arduino itself and servo motor now machine is ready to perform you need to press those push buttons to navigate between screen and to select desire data hope you will like my this project

Hello sir,I am new for electronics & programming. I like your project. I am also trying to make the same. My questions are, 1. Is it possible to input the values using 4x3 matrix keypad 2. How to insert wire sensor so as to be able to pause the running code on finishing of wireThanks in advance

@MaclskThanks for the info. I vaguely remembered a similar design I've seen a while ago and was curious why it was featured again. If you want people to make use of your inventions as long as they give proper credit, you should considering using a CC NC-SA licence or similar.

@JLGG_3D Come on, you take like 90% of the work from someone else, fail to mention it and then have the audacity to enter a contest? That feels like a violation of the unwritten makers' codex.

We actually tried making this in our shop using his PCB, and it doesn't work. There are quite a few things missing in this write up. Several components for the PCB are not listed... such as the resistors values...
